London Bakerloo line

This quiz holds 25 stations, running from Harrow & Wealdstone at one end to Elephant & Castle at the other.

Yes. It asks for the station after Harrow & Wealdstone first and works along the line. Knowing the order is the whole point, so you cannot jump ahead — but you can skip a station you are stuck on.

Yes. Both the local spelling and the romanised form count, and spaces, hyphens, middle dots and letter case are ignored. Where a name carries a bracketed alias, the alias alone is accepted too.

Each hint reveals a little more about the next station — first its opening character, then how many characters it has, then the station before it. The count stays on screen, so finishing without hints is the better run.

The list of other lines below puts the same city first. Once you have cleared the city, try a line from another country.

Type the next station in order from the terminus. Finish the word and it advances without Enter. The map follows the station you are on, and the ones behind you stay visible as clues. Romanised spellings count. Spaces, hyphens and letter case are ignored. Stuck? Take a hint or skip the station — a skip counts as a miss.

Typing “and” for & counts. Anchor on Waterloo and Charing Cross, then work back north-west towards Wembley.
